**********My First Lego Transformer Creation On MOCpages********** my lego dotm optimus prime: about 9 or 10in tall in robot form. it was my biggest lego transformer untill I UPDATED IT! Check out my V2 of this big robot. I know, I know, this V1 is not the greatest, but back when I was in like 6th grade or early 7th grade I designed this as the legit 1st version. It is ok but you can really link how much I have changed with my styles and definitely articulation. Enjoy the original!
